NAME

socketcall - socket system calls

SYNOPSIS

int socketcall(int call, unsigned long *args);

DESCRIPTION

socketcall
is a common kernel entry point for the socket system calls.
call
determines which socket function to invoke.

which are passed through to the appropriate call.

User programs should call the appropriate functions by their usual names.

socketcall.
